Cumulative of "Wrongdoings"

When it comes to using public space for own benefit, most of the people will say nothing wrong and presumbly they deserve it. This is rampant in especially house owners turf the road reserve in front of their house for parking their cars or for planting. Some even having the structure or concrete slab over the open drain. It looks like acceptable to the society norm for encroaching onto public space in front of our house or building premises. It is also commonly seen that tyres, drums, chairs or any objects be placed onto the car parking lot in front of shops as a sign of pre-booking of the public facilities, and without any payment. No businessman felt ashame for their doing which is morally wrong. There are business operators placing their products and goods on the corridor and some even blocking the passage. Some traders conducting their business on open space and some pour the waste water or kitchen waste into the drain like what many have done for their house backyard. Many people nail the signboard on trees, hang the poster on lamp post or plant the billboard on any where they like without feeling sorry to the mother earth. All these look like acceptable and can be tolerated. Are not these disconnects with liveable city cumulative negative effects to the discontent of city dwellers? Why are we so angry towards development projects and objecting emotionally? Isn't it good to treat all "wrongdoing" equally?
